CLIP DESCRIPTION:
Inspired by the bluesy atmosphere, Gary (Anthony Michael Hall) tells a group of barflies his story.

FILM DESCRIPTION:
John Hughes's third directorial effort, Weird Science, follows in the tradition of his previous teen-centered films, Sixteen Candles and The Breakfast Club. Anthony Michael Hall and Ilan Mitchell-Smith play the wannabe hipster Gary and his nebbish weak-willed best friend, Wyatt, a pair of high-school geeks who are hapless with members of the opposite sex. Using Wyatt's computer, they create what they believe is the ideal woman. A lightning storm brings that woman to life, and she takes the form of Kelly Le Brock. Lisa sets about building their self-confidence, but trouble begins brewing when Wyatt's cruel, military-minded older brother, Chet (Bill Paxton), begins to realize that something is not as it should be. Hughes would finish his cycle of high-school themed films with his next movie, Ferris Bueller's Day Off.

This song is a FREEBIE. You can stream it for free on YouTube, but also buy it at my website. I am already offering 60+ of my hip educational songs/videos on YouTube FOR FREE at youtube.com/harrykindergarten. Enjoy them, utilize them, and share them! I am a current full-time Kindergarten teacher so I know what it's like to be looking around for quality content in my classroom! You can ALSO purchase the raw video file and/or audio file of those 60+ songs at my website (if you need them for some reason) or at Teachers Pay Teachers. I will continue to make freebie videos (ones you can just stream on YouTube for free) periodically, so continue to check back to see if I've posted any.

*Please DO NOT rip any of my videos off of YouTube and upload them to your YouTube channel. I want the Harry Kindergarten Music channel to be the hotspot for these videos, not random teachers' channels who happened to illegally take them off of mine. If you really want to have a playlist of them, create a playlist from MY channel or purchase them on my website so you have the raw files. THANKS FOR UNDERSTANDING!

Q: Do you speak at conferences?
A: Yes! My ability to speak at teacher conferences during the school year is "tight" because I am currently a classroom teacher and only have a set number of personal days. However, the SUMMER time is wide-open and I'd love to come to your conference and do a session/seminar! Some of the topics I've typically spoken to teachers about include music and technology in the classroom, classroom management, running a creative morning meeting, and utilizing YouTube in the early childhood classroom. Email me at pete@harrykindergartenmusic.com to make a speaking request.

Q: Can my class perform a "Harry Kindergarten song" for an audience?
A: If you desire to have your class or group of students perform one of my “Harry Kindergarten” songs for an audience, please note that there is a $6.00 PERFORMANCE FEE.

Here are some hypothetical examples of performance groups:
* Students perform a song for an audience during a graduation ceremony.
* Students perform a song for an audience during a school or community talent show.
* Students perform a song for an audience during a school assembly.
If you are unsure if you need to purchase a performance license or not, please inquire at: pete@harrykindergartenmusic.com. If you want more details about using a song multiple years or multiple classes, etc., e-mail me for a detailed PDF file.

$6.00 can be sent to:

Have you ever heard of the law of inertia? In this Newton's First Law of Motion video for kids, you will learn about why objects either move or don't move. The first law of motion, or the law of inertia, states that objects at rest will remain at rest unless something else moves that object. It also states that an object that is moving will keep moving until something stops it.

When it comes to an object at rest, think of anything around you that isn't moving. A pillow, a book on the desk, or the desk itself. They will stay unmoved unless you, or something else, moves it. As far as objects that are moving, think of a ball in the air. Eventually the ball will fall because of gravity and air resistance. However, if it were in space, it would keep moving forever at the same speed unless it hits something or something hits it.

Speaking of gravity and air resistance, these are two natural forces that affect an object's motion. Another is friction. If you roll something across a flat but uneven surface, that object will eventually stop because of friction. Say, however, you roll something along a flat and even surface, such as perfectly smooth ice. In this case, the object you roll may not stop for a much longer amount of time because there is much less friction to stop its motion.

We hope you and your student(s) enjoyed learning about Newton's first law of motion! If you want to learn even more, head over to our website and download one of our many free lesson plans about the law of inertia, full of activities, worksheets, and more!

Types of Biodiversity
Biodiversity is the variety of life in an area which is determined which is determined by the number of species in that area.
the totality of genes, species, and ecosystems of a region
As biodiversity increases so do the health of the ecosystem increases.
Think of it as if you were running a business.
You want your business to be healthy and make money. Imagine you sell shirts. If you only sold a black shirt with a heart you are limited and if white shirts go out of style you are out of business. If you have a variety of shirts as fashion changes you are better able to adapt to these changes and continue to make money.
As biodiversity increases the ecosystem has a greater ability to adapt to changes.
Biodiversity is broken down into three types
Genetic diversity
Species diversity
Ecosystem diversity
